Do not use database DBC as the target database name in a COPY statement. Using DBC as the source database in a COPY FROM statement is allowed, but specifying a target database name that is different than DBC is required. This allows DBC to be copied from a source system to a different database on a target system. When used as the source database in a COPY FROM statement, database DBC is not linked to database SYSUDTLIB. Therefore, only database DBC is copied.
